Referring to the preferred embodiment hown in Fig, l, the roof structureconsists generally of a closed covering mounted on a structural ironframework.

The covering" -25, desire to provide a structural metal car roof hereshown consists of sheet metal plates. 1% frame of great strength anddurahility. The plates at the end are marked 47 and the These objects.and others will he made ap t l w n o plates H3. thesaid plates allparent in the following specification and ;lf -i d ogether by upturnededges and claims, takenin connection with the accom tilt h-1' Mltl jSheath-5 8 and 3O panying drawings showinga preferred cup sprrtneiy.cssrut vas per my P 'C ing striurture of the carlinos is one principalfeatures of my invention. One of these carlines is shown in detail by"Fig. 2, in which 1 is the complete carline, 9, either one of two similarand complementary component angle bars that together constitute a rarline. J the top flange of bar 2, 2" the side tiange olhar 2, -i thehorizontal middle portion of hat" 2, and .5'is one ot a group oi.clamping elements, preferably rivets, through the flanges 2'. tofastentogether the two complementary bars 2 at the central portion 4 ofthe bars that thus assembled constitute areal-line. The downwardly inframe on the line 4: of Fig. l with the eoven ing and running hoardremoved and shows particular] y one of the side plates, one. oi the 45carlines, the iridgc pole, and part of the longitudinal root iiiirsknown as purlins. The ridge pole and purlins here shown are eachcomposed of a channel iJiiI inclosing a.

wooden tiller-block. Fig. 5 is a cross sec" 50 liional view similar to lig. -i except. the inverted position oi therii ige pole and slightminordetails. Fig. (3 is also a cross sectional view similar to Fig. texcept the inverted position of the ridge pole and pur- 56 has, which inthis themost preferred eniturned transversely and toward thecomplementary member. The point where the -.flange ends 8 and 9 bendfrom alinement 'with the adjacent bar body and divergent.

from each other is'marked 10. The flange end 8 is perforated by a hole11 and flange end 9 is provided with holes 12. The inclined portion offlange 2 is provided with holes 13 and the horizontal part of flange 2is provided with a hole 14. These holes are adapted for engagement withbolts, rivets or the like for fastening to other parts of the frame androof. i

The main outer framework for the roof consists of two side plates 16 andtwo end plates 15 fitted together in rectangular shape. On the upperside of each side plate are furnished filler-blocks 17 so as to providean inclined upper surface to engage the roof covering. Thesefiller-blocks are provided withjsp ces 18 to admit the flange ends 8 forfas ening to the side plates 16 by means of the/ bolts 3, as shown byFig. 3. ,"Each fillergblock, 17 has a flat horizontali inder side,21 toengage the top of the side p .ate 16, an inclined upper surface 20 toengage with In Fig. 1 bolts 22 are shown for fasteningthe roof and avertical inner face 19.

the flange ends 9 to the plates16. The bolts 3. are also here shown. Theridge pole 23 is shown centrally located and supported on the carlines1, where secured by the bolts 45.

- -In' this embodiment shown by Figs. 1 and 9 these bolts 45 extenddownward through the running board 24, saddle block 25, ridge sheath 49,ridge pole 23, and carline flange 2'.

I prefer generally to use separate means 42 for fastening the ridge poleto the carlines as shown in Figs. 4, 5, and 6 and then the bolts forfastening the running board, saddle block and ridge sheath to the ridgepole ma be distributed along the ridge irrespective of the carlines. Thepurlins 2 9 are suitably distributed on each side of the ridge pole andfastened by suitable means such as bolts or rivets 30 t0 the carlinebars The ridge pole 23, which in its preferredembodiment, as shown inFig. 6, consists chiefly of a channel bar, has its side flanges 40 cutaway at the ends and the end 43 ofits web 39turneddown at the point 37over the end plate 15 and secured by suitable means,

such as bolts through the holes 44, shown in Fig. 4, the end sheathing38 being recessed to receive it as shown in Fig. 8. The purlins are alsoformed and secured'at their ends in a similar way. Several embodimentsof ridge pole and purlin construction are shown by Figs. 4, 5, 6 and 11,Fig. 6 showing the one I prefer.

The ridge pole and purlins shown in Fig. 6 each consist of a metalchannel bar only and in Fig. 11 they are made of wood only while inFigs. 4 and 5 theyeaeh consist of a channel barcontaining a filler blockof wood.

In Fig. 4 one end of a carline 2 is shown attached to the side plate 16and supporting the wood-filled channel bars constituting the 'purlins 29and ridge pole 23. Each purlin channel 31-32 is shown with its flanges32 cut away and its web 31 turned downward at the end 35 and rovidedwith perforations 36 to engage'wlth means for fastening to the end plate15 in a. manner similar to that by which the web of the ridge polechannel is turned downward at its end 43 and provided with perforations44, for bolts or the like as aforesaid. The purlin fillerblock is marked33 and ridge pole fillerblock 41.

' Fig. 5 is similar to Fig. 4 except that theridge pole is inverted sothat its channel flanges turn downward instead of upward.

The embodiment of Figs. 6 and 7 diifers from those of Figs. 4 and 5 onlyin that the ridge pole and purlin channels are all devoid offiller-blocks and all have their flanges turned downward, the saidflanges being trimmed away at the points of engagement with the endplates and carlines so as to give the channel webs direct bearing on thecross elements. The flange 2 of the carline then fitsin the notches 34in the purlin flanges 32 and in similar notches 56 in the ridgechannelflanges 40.

Fig. 11 showing the use of plain wooden purlinsand ridge pole is similarto Fig. 4 except that all channel bars are omitted. This provideslightness of construction where the greater strength of channel irons isnot required. a

Figs. 9 and 10 show longitudinal and transverse sections respectively ofthe roof assembly. Fig. 9 shows the roof framework of Fig. 11 inconjunction with the sheet metal roofing and running board as describedin my previous patent aforesaid. The metal roof' plates 46 with theirupper inward edges 46 hooked and nearly abutting and with their lowerouter edgesresting on theside plate filler blocks 17 are shown in Fig.9. The said inner hooked edges 46 are locked by means of the ridgesheath 49. The side edges 46 are also similarly hooked and locked by thecross sheaths 48. The outer end of 'each cross sheath is secured by adownwardly turned end 55 fastened to the side of the car bya bolt 54 asshown in Figs. 1 and 9. Each end 53 of the ridge sheath 49 is likewiseturned down and fastened by a bolt 53.

All-outer edges of the roof plates 46 and strips across 47 adjacent tothe edge of the roof are clamped in place by'the clips 5051' and 50'T51the latter being used at the roof corners. Each clip has tongues 51 toengage the roof plates and a main downwardly turned part 50 or 50'respectively equipped with screws 52 ,or the like to engage with theside of the car.

A running board is provided as shown in Figs. 9 and 10. v This consistsof the several 24 attached to saddle blocks 25 placed the ridge sheath49. Each block is fitted on its under side with a middle surface 27 toengage and rest on the ridge sheath 49, and with inclined surfaces 26 toengage with and rest on the cross sheaths 48.

Bolts 45 are provided to extend downward ;.through the center of therunning board 2-1,

the saddle block 25, sheath 49 and ridge pole '23, thus to lock theparts securely together.

. While .I have herein shown and particularly described some embodimentsof m vention, I ,do not wish to limit myse f to the preciseconstructions as herein shown and particularly described as manymodifications may be made b those skilled in the art without departingrom the spirit of iny said -invention. 4
